Surat is a great host: very present and helpful.
The house is best placed to reach the main sightseeings and located in a very nice area to enjoy the authentic Bangkok: there are almost only local people around, market and street food stalls are right on the street, the prices (also for taxis and tuk tuk) are fair and the people very friendly (and not pushy).
We had a great stay and warmly recommend this place.
